Application filed May 24, 1917. Serial No. 170,693.

To all whom it may concern:

Be it known that I, MARCUS Hoors, a citizen of the United States, residing at Springview, Nebraska, in the county of Keyapaha and State of Nebraska, have invented certain new and useful Improvements in Means to Prevent Freezing of the Water-Cooling Systems of Automobiles, of which the following is a specification.

This invention relates to means to prevent freezing of the water cooling systems of automobiles.

One object of my invention is to provide an appliance which may be readily installed in automobiles or other motor driven vehicles for the purpose of facilitating the circulation of water in the water cooling system and to prevent freezing of the water in cold weather.

Another object resides in the provision of an appliance of the nature stated, embodying among other characteristics, means whereby the products of combustion from the engine may be utilized for the purpose of heating the water in the water cooled system of the engine to prevent freezing of the water in cold weather and which is so constructed that the products of combustion utilized for the said purpose may be directed through the usual exhaust of automobiles so that the appliance need not be dismounted in warm weather.

With the above and other objects in view, the present invention consists in the combination and arrangement'of parts hereinafter more fully described, illustrated in the accompanying drawings and part cularly pointed out in the appended claims, 1t being understood that changes may be made in the form, size, proportion and minor details without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings Figure 1 is a side elevation of one embodlment of the invention;

Fig. 2 is a to plan view;

Fig. 3 is anot or side elevation;

Fig. 4 is a detail sectional view of the auxiliary heating chamber;

Fig. 5 is a side elevation of another embodiment of the invention;

Fig. 6 is a side elevation of the second embodiment of the invention; and

Fig. 7 is a front view of the second embodiment of the invention.

Referring now to the accompanying drawings, and more particularly to Figs. 1 to 4, inclusive, the reference character 10 mdicates an engine of an automobile or other motor vehicle which has water pipe connection 11 and 12 with the radiator casmg 13, the water pipe connection 12 Having an outlet valve 14 whereby the radiator may be drained when desired.

I propose to heat the water in the radiator and consequently throughout the water heating system of automobiles and the like to prevent freezing of the water in cold weather, especially in the radiator, by the application of heat to the lower portion of the radiator.

In one embodiment of my. invention, I secure'a heating chamber 15 to the radiator casing 13, preferably against the inner side of the radiator casing. As shown, this heating chamber 15 may be of a length substantially the width of the radiator casing and it may be secured to the radiator casing in any suitable manner, and as shown, I locate said chamber at the inner side of the radiator adjacent the lower portion thereof. A plate 16 is disposed against the outer side of the radiator at the lower portion thereof. This plate 16 is of a width and length substantially the same as the width and length of the heating chamber 15. Through this plate 16 and through the radiator casing and the heating chamber 15, suitable bolts 17 may be passed in order to secure said plate and said heating chamber firmly to the lower portion of the radiator casing. The particular arrangement of this plate 16 and the heating chamber 15 provides for a dead air space 15 at the bottom of the radiator casing, keeping out drafts of cold air and facilitating heatmg of the lower portion of the radiator.

As a heating medium, I utilize the products of combustion from the engine, connecting to the exhaust manifold 18 of the engine 10, suitable pipe connections 19 which establish communication between the exhaust manifold 18 and one end of the heating chamber 15.

Valves 20 and 21 are located in the exhaust manifold 18 for the purpose of regulating the supply of the exhaust gases to the heating chamber 15 and these valves are.

adapted to be operated by the-driver of the vehicle by means located on the dash 22 of the vehicle. For instance, the valves 20 and 21 have arms 23 and 24: respectively, which are comected together by means ot link 25 pivotally connected thereto there being a push rod 26 connected to the pivotal joint between the arm 23 or the valve 20 and the connecting link 2-5, said push rod 26 extending through the dash 2:2 and having an operating knob or handle 27, as shown. These valves are mounted. and arranged with relation to each other so that when one valve is closed the other valve is opened. in cold weather the valve 21 is opened to allow the hot gases from the exhaust pipe to go for ward into th heating chamber l5, hen this valve 2i is open to permit the exhaust gases to go torwardly to the heating chain her 15, the valve 20 is closed to cut ed the flow oi"- exhaust gases through the exhaust 28.

The hot gases passing into the heating chamber 15 tlow through the heating chamher from one end to the -other thereot and exhaust from the end opposite the end through which the hot gases are admitted to said chamber. At the exhaust end of the chamber are two exhaust pipes 29 and 30 which straddle the water pipe 12 and which are connected at their outer ends by a f or other suitable coupling 31 from which leads a single exhaust pipe 32 to exhaust the prod ucts ct comhustionto the atmosphere.

An auxiliary heating chamber surrounds the exhaust pipes 29 and 80 and also the lower portion of the pipe L. This auxiliary heatingchamber re'aine the heat d et ing rom exhaust pipes 29 and 30 l Clll tating the application of heat to the water cooling system of engine. his ttllKllv iary heati chamber he ahle construction hut shown, 1 1111381 and lower sections 3 an E l espect *ei F each section being I s tially seinrcircular form in or ss sectio i and 1 flanges 35 wherebv the sections may he hol ed together. he lower section 34: is lcneer than the upper section 53 and its from; one extends under the radiator to the extreme lower portion of the water pipe 32, there being an o ening 36 in the section 4 to permit projectioi therethrough of the pet cohi: or outlet valv fl opening 37 A Q in the th v 7 scribed need not he removed from the ma-= chine, but permitted to remain on the machine because by closing the valve 21, the connection between the valve 21 and the valve 20 will result in the valve 20 losing opened so that in warm weather, the prodnets of cornhustion may pass backward through the common e aust 28.

ln anoth r embodiment of my invention the radiator 13 is provided with a lower water chamber 38, there being suitable water conducting passages 39 and to between the engine and the radiator and the lower water chamber 38, respectively, as shown. rom this water chamber 88 leads a valve or pet coclr ll. To the under side of the water chamber 38 l secure one form of my heating chamber which may be secured to the radiator in any suitable manner, but as shown by means of suitable clips 4:3. lhe products or" combustion are let into the heat chamber l2 at one end through pipe connections from the exhaust manifold pipe in the same manner as in the form first described. In this second form of the invention, however there is out one exhaust pipe leading from the heating chamber 41- this exhaust pipe is indicated at ti and leads from the end of the heating chamber opposite the end at which the products out combustion or exhaust gases enter said charnhe This outlet 44 oi the heating inher leads into an auxiliary heating the water pipe L0 to further heat the water in the system of the machine and the products of combustion entering the through a short pipe l. l muifler (not may he secured to the pipes 32 and lesired,

n hotiterms of my invention, it will he understooo. that the same may be readily plied to automobiles and readily disconnected therefrom and that without removal of the applia so from the machine the prodnets of" combustion may be prevented from "h the usual common muttler or ex means of push rod 26 on dashw claim is:
